We ran SNID-SAGE and found the top 10 closest matches are TDEs (closest match is TDE 2018fyk) at redshift 0.088, consistent with the redshift reported in AstroNote 2026-87. The classification is primarily based on the broad HeII feature at 4685 angstroms (rest wavelength), consistent with the line reported in AstroNote 2026-93. 2026TNSCR1657....1F
